1. A power conversion system, comprising:

  • a single-phase AC power source for generating an AC power;

    an AC/DC power converter connected to said single-phase AC power source for converting said AC power into a DC power;

    a main smoothing capacitor connected to DC terminals of said AC/DC power converter;
